Probably the easiest way to do this is to Import the MOV footage, and then drag one to the New Icon, to create a Sequence that matches that footage. Drag the rest to that Sequence, and tighten things up, as required.

Then, the Export Settings will depend on how you wish to "deliver" the file. If BD, then use Adobe Dynamic Link to Import it into Encore, and do any navigation that you might want. Burn to BD and use a BD player.

If you wish to do other for delivery, let us know, and someone can give you the best Export Settings.
